6. Higher the temperature lower the power output of PV module Comparing with pole mounted PV module array roof mounted PV module array generates less power due to less air circulation and excess heat from roof top Important The inverter will reduce its output generation to protect its electronic circuits from overheating and any damage under high temperature environment For maximum power output in high temperature it s recommended to mount the inverter in a shaded location with good ventilation Angle of the Sun The angle of the sun in relation to the PV array surface the array orientation can dramatically affect the PV array output The array energy output will vary depending on the time of day and time of year as the sun s angle in relation to the array changes Sunlight output decreases as the sun approaches the horizons such as in winter in Europe due to the greater atmospheric air mass it must penetrate reducing both the light intensity that strikes the array s surface and spectrum of the light In general you can expect only four to six hours of direct sunlight per day depending on what part of Europe the inverter is installed Partial Shade Shading on a single PV module of the array will reduce the output power of the entire system Such shading can be caused by something as simple as the shadow of a utility wire or tree branch on part of the array s surface This condition in effect acts like a weak battery in a flashlight redu
